This item qualifies for FREE Shipping in the continental United States!

The K&N Air/Fuel Monitor is designed to help with jetting or injector settings on any engine running on unleaded gasoline, alcohol, propane or nitrous oxide. The 3-color LED gauge displays your engine's air-fuel ratio from Lean to Rich.

This round in-dash unit mounts in a two inch hole like any standard guage for a permanent, professional appearance. This complete kit includes an oxygen sensor, weld-in threaded bung, and blanking plug (for running without the sensor). If your vehicle is already equipped with a one-wire oxygen sensor, you can just tap into the existing sensor wire rather than installing a separate sensor.

The monitor can be used for short periods of time with leaded fuel, but the sensor must be removed after "dialing in" the engine to prevent the oxygen sensor from becoming clogged. A partially clogged sensor can sometimes be cleaned by carefully heating it with a propane torch if the coating is not too severe.
